Hi Doctor's, I'm 31 years old male, I had lots of pimple on my face before few year back due to which deep scars are on left and right side of chicks which make face ugly, I tried dermalogy using roller to remove scar but it doesn't help me and I wasted too much money. One of doctor from lybrate suggested to use nihilinum 1m/ 5 drop in water. What is a nihilinum? and where I can get this, is there any side effect of using this? kindly suggest me waiting for your reply.
